I have a 97 jeep grand Cherokee, when it has sat for over an hour it takes 8-10 seconds of the starter running before it starts. If turned off after running, and started within a few minutes no problem,...


Fuel pump. The valve in the pump that stops the fuel from draining back into the tank is not working so you crank and crank until the fuel gets up front. Turn the key on but not to start for 5 seconds then off do it five times and then try to start it should start right up

Put new alternator and battery in 1995 Buick Lesabre with key pass will turn over and run afew seconds but wont stay running


actually a pretty easy fix. The pass key computer lost its programming. Put the key in and leave it on with the security light flashing. Just turn off all your accessories and make sure battery is pretty good charge. Anyway after you leave the key on for ten minutes the security light will come on steady so turn key off and right back on and start car. If security light still starts blinking and car stalls then do it again. It will usually work the first time but can take a few times to get it right.

Changed fuel pump and fuel filter.. how do I get all the air out of the lines


When you turn the key on, you should have fuel pressure. If not, something is not right. (The fuel pump should cycle for a few seconds when you first turn on the key to "run")

THE FUEL PUMP HAS NO POWER GOING TO IT 1997 GRAND CHEROKEE FUEL PUMP NOT WORKING AND NOW POWER IS GOING TO IT THRU THE WIRING


ok the pump will only have power going to it for a few seconds when you first turn the key to the run pos. or if your trying to start the engine. after that you must cycle the key to get power to go back to the pump. so have someone turn the key to the run pos and with your test light or volt meter on the power wire to the pump see if it lights up. it should only stay lit for a few seconds. if you ge power for a few seconds you know you have the right wire. if none of the wires have power like that check the relay and fuses. if they check out to be good check all your wiring that pertants to fuel system if all is well you could have a igni issue.

Takes multiple times to start


I think you have a faling fuel pump or a bad pressure regulator allowing fuel pressure to bleed down when the engine is off.
Try this test - When you start the car for the first time of the day, turn the key to "ON", wait a few seconds, turn the key off. Wait about 15 seconds, turn the key to "ON" again, wait a few seconds. Then wait one final time for 1 seconds and try starting the car. If it starts right away, that means fule pressure is bleeding of due to a bad check vavle int he fuel pump, a bad fuel pump or a bad pressure regulator.

The reason for the procedure is because when you turn the key to "ON", the fuel pump runs for 2 seconds and then shuts off if the engine is not running. The 15 seconds wait is for the power and fuel pump relay to cycle off before it will run the pump again.

Let us know how the test comes out. The fuel pump is in the fuel tank and hums when it is running.
